What Peridot Is?
Peridot is the gem variety of olivine, one of the most abundant minerals inside the Earth.
Olivine makes up a large share of the upper mantle. When it grows clear and green enough to cut, it becomes peridot.
In other words, most peridot is a piece of the inside of the planet.

Peridot Colour and Value
- Pure grass green – No yellow or brown cast; considered the highest-value peridot color.
- Bright lime green – Has a slight yellow tone; regarded as high value.
- Olive green – Features a noticeable yellow-brown tint; considered moderately valuable.
- Brownish green – Appears muddy under normal light; generally has the lowest value.
Size matters too. Peridot stays very affordable up to about three carats, then prices climb sharply.
Why Peridot Is Only Ever Green
This is the fact most guides state without explaining.
- In most gems, colour comes from trace impurities. Amethyst is purple from iron traces in quartz. Emerald is green from chromium traces in beryl.
- In peridot, iron is part of the core chemistry, not an impurity.
- Remove the impurity from other gems and you get a colourless stone. You cannot do that with peridot.
- Result: peridot occurs in exactly one colour.
Buyer warning: there is no blue peridot, no pink peridot and no rare purple peridot. Any seller offering one is misrepresenting the stone.

Where Peridot Comes From
| Source | Note |
|---|---|
| Zabargad, Egypt | Oldest recorded source, located in the Red Sea. |
| Pakistan | Famous for Himalayan deposits producing large, high-quality crystals. |
| China | One of the world's major commercial suppliers of peridot. |
| Myanmar | Known for producing peridot with exceptional color and clarity. |
| Arizona, USA | Historically significant source, especially from the San Carlos Apache Reservation. |
| Tanzania & Vietnam | Modern mining regions with ongoing commercial production. |
| Pallasite Meteorites | Extremely rare extraterrestrial source containing gem-quality olivine crystals. |
Peridot in History
- 340 to 279 BCE Mining likely begins on Zabargad island in the Red Sea, then called Topazios.
- 2nd century BCE Peridot appears in priests' jewellery.
- Ancient Egypt Called the gem of the sun. Worn as a talisman against evil spirits and night terrors.
- Cleopatra's era Many historians believe her famous "emeralds" were actually peridot.
- Medieval Germany The Shrine of the Three Kings in Cologne Cathedral is set with roughly 200 carats of peridot, believed for centuries to be emeralds.
- Today Zabargad's old name, Topazios, is why topaz carries the name it does.
Zabargad was known as the Island of Death. No fresh water, no shelter, venomous snakes and extreme heat. Miners were reportedly kept there under guard.
Peridot From Space
Peridot is one of very few gems that also arrives from beyond Earth.
- Pallasite meteorites are a rare stony-iron type made of nickel-iron metal with olivine crystals suspended inside.
- When those crystals are clear and large enough, they are gem-quality peridot.
- Only a handful of pallasites have ever produced cuttable material.
- On Earth, Papakōlea beach in Hawaii has green sand made largely of olivine grains.
Spinel: The Modern August Birthstone
Why Spinel Was Added
Spinel joined the August list in 2016, giving August birthdays a harder and more colourful option.
At 8 on the Mohs scale, spinel is considerably tougher than peridot and suits daily-wear rings.
The Black Prince's Ruby Is Not a Ruby
Red spinel was mistaken for ruby for centuries.
The most famous example is the Black Prince's Ruby, roughly 170 carats, set in Great Britain's Imperial State Crown. It is spinel.
Sardonyx: The Ancient August Birthstone
What Sardonyx Is
Sardonyx combines two forms of chalcedony: reddish-brown sard banded with white or black onyx.
Why Romans Used It for Signet Rings
Hot sealing wax does not stick to sardonyx.
That single property made it the Roman material of choice for signet rings, because the seal lifted cleanly every time. It has been a favourite cameo carving stone for millennia.
